1 Claim.

The present invention relates to building construction, and particularlyrelates to trim to be used around doors, windows and in similar places.

An object of the invention is to provide a device which can be deliveredon the building site with all Visible parts factory-finished and whichis capable of quiclr and simple mounting after completion of thebuilding work, whereby damaging of the visible surfaces of the trim isavoided.

Another object is to provide a device which enables interchange of theside parts of the trim, if it is desired to `change the door to beopened in the opposite direction to that vin which it is originallymounted.

Another object is to provide a trim which does not display any nail orscrew heads, but presents an even surface free from vcracks and similarmarks which frequently occur in the traditional wooden frames andwhich-may be kept in place by means of invisible screws, the only toolnecessary for mounting the whole device being, in fact,a screw-driver.v

Further objects of the invention will be evident from the followingdescription and the drawings relative thereto.

Our invention can be explained in greater detail by reference to theaccompanying drawings which show more or less diagrammatically theconstruction and assembly of the various parts of our invention. In thisshowing,

Fig. 1 is an exploded view in perspective of a door opening showing themolding and trim members of our construction from which the manner ofassembly is obvious.

Fig. 2 is a perspective view of a corner of our construction showing thetop trim member and a side trim member assembled and with dotted linesto show the manner in which the side member is put in place,

Fig. 3 shows all of the members in assembled position including a doorwhich is in closed position, f

Fig. 4 is a horizontal section taken on the line 4 4 Aof Fig. 3,

Fig. 5 is a vertical cross section taken on the line 5 5 of Fig. 3,

Fig. 6 is a fragmentary view in perspective 0f the top portion of theside trim member carrying a projecting lug for' attaching the moldingmember, showing the construction of the lug,

while Fig. 7 is a perspective view of the inner side of the channelshaped molding member showing a metal strap which cooperates with acorresponding lug of the molding member to secure the molding member tothe trim member.

The device according to the invention is suitably composed of four mainparts, namely a rough wooden frame inserted in the door-passage or ifdesired beingpart of the wall when this latter consists of wood; theactual trim of U-shaped sheet metal, e. g. sheet-iron; moldings of woodor other suitable material, and a sill of oak or other suitablematerial.

In the various views of the drawings in which like parts are designatedby like reference numerals, the frame l may suitably consist of plainwood, which need not be planed since it is completely covered by theother factory-finished parts. It should preferably be impregnatedagainst moisture, rot and other destructive attacks and may obviously bemade of cheap material. Grooves I2 are preferably factory-cut into thevertical parts of the rough frame, at the bottom for the sill, at thetop for the upper part of the sheet-iron trim and on the sides for thedoorhinge plates, so that the door can be hung on any side desired. Inwooden walls the rough frame can be entirely omitted. as alreadyindicated, the metal trim being simply` attached to the edge of the.wall surrounding the door-opening which in itself forms a wood framefor said opening.

.The ytrimy suitably consists of three stove-.lacquer nished,substantially U-shaped sheet-iron proles 3, li, 5 which are pushed overand screwed onto the rough frame as shown in Figs. 2, 4, and 5. Theseparts are preferably out from the same prole, one of the vertical pieces4 being provided with the door hinges l l riveted or welded thereto, theother vertical piece 5 being provided with a hole i 0 for the bolt ofthe door-lock. A soundabsorbing material l5 such as felt, wood or glasslibre or similar is suitably glued to the back side of the profiles.Ear-shaped fastenings or lugs 9, shown best in Fig. 6, are welded to orin some other suitable way rigidly connected to the parts 3, 4, 5. Thesefastenings cooperate with corresponding members, e. g. in the form ofmetal straps I3, fastened to the back of the moldings l (Fig. 7) for thetop part 3, and to S for the side parts f2., 5 of the trim. The trim issuitably lixed to the frame i by screws through holes i4 in the ears 9,these latter thus serving to hold the trim as well vas the coveringmoldings for this. Instead of with straps the moldings '1, 6 may beprovided with other fastening means such as buttons or spring hookscooperating with corresponding members on the trim, so that the moldingsmay be put in place and removed at will, without showing any suchfastening means on the front side.

The sill 2 is no integral part of the construction and may be left out.In that case the corresponding lower cut-outs l2 should of course alsobe left out.

The mounting of the device according to the invention is a very simpleand quick procedure:

The sill 2, if any, is rst inserted in its grooves l2 in the rough framel and xed with a screw at each end, these screws subsequently beinghidden by the trim. The upper part 2 of thetrim is next inserted in itsgrooves and pushed somewhat upwards, so that suicient space is left forthe side pieces 4 and 5 to be put in place without scratching as shownin Fig. 2. The member 4 lcarrying the hinges is then put into place andfixed to the frame i with screws through ears 9. The door is hung.Member 5 is now set, the door is closed and member 5 adjusted against itand then fastened to the frame l by screws through the correspondingears 9. The upper part 3 of the trim is now pushed down tightly againstthe side pieces so that it ts the door` and is then attached to the toppart of the frame I by screws through ears 8. Finally the moldings arehooked onto their fastenings which are shaped so that the moldingsbecome tightly pressed against the wall and the side of the trim. Thejoint between wall'and rough frame as well as the edge of the trim arethus covered by the moldings as shown best in Fig. 3.

Instead of sheet iron and wood moldable plastics or other materialssuitable for stamping or pressing may also obviously be used.

The invention is not limited to door trims but may in principle be usedfor other building details such as windows, closets andthe like.

We claim:

An adjustable door trim for a door frame hav- Y ing stile members and ahead, comprising a channel-shaped top trim member, a pair ofchannelshaped side trim members adapted when mounted to abut against theunderside of said top member at right angles thereto, projecting lugsmounted integrally along the edges of said channel-shaped top and sidemembers, said lugs being provided with extensions providing moldingfastening means and with means for adjustably securing saidchannel-shaped members to the door frame, said channel-shaped top memberhaving a length which is greater than the inside width of said doorframe, said stile members having slots just beneath the head ofysufficient width and depth to permit insertion of the channelshaped topmember and to permit adjustment of same both vertically andhorizontally, a channel-shaped top molding, a pair of channel-shapedside moldings adapted when mounted to abut against the underside of saidtop molding at right angles thereto, fastening elements mounted on theinner sides of said top molding and said side moldings and cooperatingwith the extensions on said channel-shaped trim members to removablysecure said moldings over the edges of said channel-shaped trim membersto cover and conceal said edges and said securing elements, and doorhinges mounted on one of said channel-shaped side members.
